The enclosure measures roughly 11.8 metres north to south and 8 metres east to west, enclosed on its eastern, southern, and part of its northern sides by a stone wall standing about 0.75 metres high and 0.6 metres thick. One side remains open, the wall simply ending, as if the boundary were never quite finished or perhaps never needed to be.

Local knowledge identifies this as a cillíneach, a type of unofficial burial ground once found across Ireland, used for the interment of unbaptised children. Catholic doctrine held, until relatively recently, that infants who died before baptism could not be buried in consecrated ground, and so communities created their own quiet places at the margins, often within or near ancient earthworks, on liminal ground, or, as here, on a sheltered terrace in a field. The word cillíneach derives from the Irish word for a small church or cell, though these sites had no ecclesiastical sanction. They represent a folk response to an institutional exclusion, and they are found in every county in Ireland, often unmarked and unrecorded except through the memory of neighbouring families.
